Question: How old are you when you realize that you're autistic?

Although I'm (16 years old male almost turn 17 on Oct 8), I was diagnosed at 5 years old (in 2014) but I don't realize I'm autistic until I'm 14 years old (in 2023) when I learned about ASD at school or phone and I tell myself "I.. I'm... Autistic?!?!"

Story about my autism: I started having autism when I was 2 when I didn't speak any word until I'm 7 years old so my parents sent me to a special school for those who have autism but I stayed in the same special school for decades, at least I can focus, I really wanted to go to new school but my parents said "Later" "Next year" "after something" like I've been delayed again and again and I feel different from other 17 years old and I always compire myself to others, I can still focus on studying and other things, I do eye contact (rarely I avoid), rarely sensitive to loud noise and etc I have level 2 autistic but I'm very good at English but my native language (Arabic) is sometimes harder and I can't read Arabic but I can speak Arabic anyways, sometimes I had anxiety and depression, I'm sometimes struggling with communication but I'm hyper focus and can think deeply

Well that's it...
